I took a norco 10/325 at 4:30 pm, and again at 5 pm when it was time for me to take a different prescription. I simply picked up the wrong med and didn't realize it until immediately after I swallowed it! Should I be concerned? I take a lot of prescription medication, much of which has a moderate interaction of depressing my central nervous & respiratory systems. I am planning not to take one of my as needed meds that I was going to take so as to prevent any extra cns or respiratory depression. But could anyone with experience in this area please let me know if I should be worried about the accidental double dose of norco (20 mg hydrocodone and 650 tylenol)... Thanks!
